Abstract
Chloroform as a carcinogen removal by surface‐modified activated carbon from an aqueous solution was investigated for the assurance of safe water.
Surface hydrophobilized activated carbon by hydrogen gas adsorbed the largest amount of chloroform. To elucidate the dominant factor of adsorption removal of chloroform, correlations between the amount adsorbed and physicochemical properties of adsorbents. A significant inverse correlation was recognized between the amount of chloroform adsorbed and the base consumption.
It was found that the existence of acidic groups on the surface of activated carbon inhibits the adsorption of chloroform. It was concluded that the suitable adsorbent for chloroform removal was an activated carbon with more hydrophobic surface.
